Williamson County Addressing

Williamson County GIS & Addressing staff provides the addressing for the unincorporated areas of the County as well as for several of the smaller incorporated Cities. Our addressing staff is currently awaiting final approval of Williamson County 9-1-1 Addressing Guidelines, however; the draft version can be located here

In addition, the staff maintains the master address database that drives the 9-1-1 telephone system for the entire County.

If you need to obtain an address (to get telephone service, utility hook ups etc.) please contact the Addressing Staff.

Looking for information regarding street names?


Williamson County Addressing Department does not allow street names that are duplicated in the County. There are two ways to verify if a street name is in use or reserved. PLEASE keep in mind that all street names in the County must still be approved through our office, these are just provided to help expedite service in selecting street names.

Click Here to Search Current Street Names

Click Here to Search Current Reserved Street Names (This will be in an Excel Spreadsheet)

The Excel spreadsheet is broken down by City or County tabs (listed at the bottom- make sure to search within the entire worksheet) for Reserved Streets Only. 

For more information, please contact our Addressing Department.
